The film “All Good Things” will be in theaters next month, with a fiction-fused account of the mysterious past of Robert Durst, the eccentric New York millionaire acquitted in 2003 of murdering his Galveston neighbor.

The movie, starring Ryan Gosling and Kirsten Dunst, will open Dec. 3 in New York City, Dec. 10 in Los Angeles and later in the month at other venues. The Angelika Film Centers in Dallas and Plano will show the film starting Dec. 17.

“We will add play dates as we go along; keep checking the website,” said Dana Vladimir, manager of marketing and publicity at Magnolia Pictures, film distributors.

The plot revolves around a love story and murder mystery loosely based on Robert Durst’s life in the 1970s and 1980s, years before he would go to trial for the shooting death of his 71-year-old Galveston neighbor, Morris Black. Galveston might be a setting for a few scenes, but no filming was done on the island.

The plot draws on details of the real-life missing person mystery of Kathleen Durst, the first wife of Robert Durst, eldest son of a New York real estate tycoon. Mrs. Durst disappeared in 1982.

Durst was investigated but never charged in the disappearance. Some 18 years later, he would make his way to Galveston. He claimed he had heard New York police were reopening the case and targeting him as a suspect.

In Galveston, Durst would be charged with the murder and dismemberment of his next-door neighbor. He pleaded not guilty by reason of self-defense, testifying a struggle over a gun led to the fatal shot. He admitted panicking and cutting Black’s body into pieces, which he dumped in Galveston Bay.

He was acquitted of the murder charge in 2003 but would spend almost five years in jail before, during and after the trial on other charges.

The film, “All Good Things,” does not focus on the Galveston murder, but a fictionalized version of Durst’s life and his wife’s disappearance 20 years earlier.

Gosling acts the part of David Marks, son of a New York real estate tycoon. In the film, he is scarred by the memory of his mother’s suicide, witnessed at an early age.

Release of the movie prompted threats of a lawsuit by The Durst Organization for the film’s depiction of the family, according to an Oct. 27 article in The Wall Street Journal. Robert Durst has been estranged from the family since 1994.
